One Piece TCG rotation: the Block system, Standard and Extra
In April 2026 One Piece stopped being an eternal format. Here is what the block icon on your cards means and which of your decks still work.
The short version
- Since 1 April 2026 the One Piece Card Game has two official formats: Standard Regulation, which uses the Block Number System, and Extra Regulation, where everything is legal unless banned.
- Sets are grouped into blocks of four main boosters: Block 1 is OP-01 to OP-04, Block 2 is OP-05 to OP-08, Block 3 is OP-09 to OP-12, Block 4 is OP-13 to OP-16.
- Standard Regulation keeps the three most recent blocks legal, giving roughly three years of card pool, and rotates the oldest block out about once a year.
- The block number is printed in the lower-right corner of the card, so you can check legality without looking anything up.
- Cards that rotate out are not dead: they stay legal in Extra Regulation, and a reprint carrying a newer block icon becomes Standard-legal again.
For its first three years the One Piece Card Game had the simplest legality rule in the hobby: every card ever printed was legal unless it appeared on the banlist. That ended on 1 April 2026. The game now has two formats, and the one most events use has a rotating card pool.
This is a bigger change than a banlist update, because a banlist removes cards one at a time and a rotation removes them by the hundred. If you own cards from the earliest sets, it is worth understanding exactly where they now stand.
How blocks are numbered
Main boosters are grouped into blocks of four. Every card carries its block number as a small icon in the lower-right corner of the frame.
| Block | Main boosters | Standard status |
|---|---|---|
| Block 1 | OP-01 – OP-04 | Rotated out of Standard |
| Block 2 | OP-05 – OP-08 | Standard legal, oldest legal block |
| Block 3 | OP-09 – OP-12 | Standard legal |
| Block 4 | OP-13 – OP-16 | Standard legal |
| Block 5 | OP-17 onward | Standard legal from release |
Standard Regulation
Standard is the format the game is built around and the one nearly every sanctioned tournament uses. It keeps the three most recent blocks legal, which works out to roughly three years of releases. When a new block begins, the oldest legal block rotates out.
The practical effect is a format that refreshes without Bandai having to ban anything. Cards that dominated for two years leave on a schedule instead of by intervention, which is a much less disruptive way to move a metagame — and it is why other long-running card games adopted the same mechanism.
Extra Regulation
Extra Regulation is the eternal format: every card released to date is legal except those on the banned, restricted or banned-pair lists. It exists precisely so that rotation does not turn a collection into cardboard. If you have a deck built from Block 1 cards, it still has a home — you just need to find events running the format, which are less common than Standard events in most regions.
| Standard Regulation | Extra Regulation | |
|---|---|---|
| Card pool | Three most recent blocks | Everything ever printed |
| Rotation | Yes, roughly annual | No |
| Banlist | Applies | Applies, and is larger |
| Event coverage | Nearly all sanctioned events | Occasional; varies heavily by region |
What rotation does to card prices
This is the part collectors ask about, and the answer is less alarming than it sounds — but it is real.
- Competitive staples fall when they rotate. A card whose price was driven by tournament demand loses that demand on rotation day.
- Collector cards barely move. Alternate arts, Manga Rares and Secret Rares are priced on scarcity and art, not legality, so rotation touches them lightly.
- Reprints reset the clock. A card reprinted with a newer block icon is Standard-legal again, and the reprint's arrival usually depresses the original printing's price.
- Rotation is announced well in advance. Bandai signalled the block system months before it took effect, so this is not a risk that arrives without warning.
Rotation does not delete cards. It moves them from one format to another, and moves their price from tournament demand to collector demand.
How to check whether your deck is legal
Checking legality in two minutes
Look at the bottom-right of every card
The block icon is printed there. Any card with an icon inside the currently legal range is fine for Standard.
Check the Leader separately
Leaders rotate like anything else, and a rotated Leader takes the whole deck with it. Check it first, because it is the card that decides whether there is anything to fix.
Cross-check the banlist
Block legality and the banlist are separate filters, and a card has to pass both. See our banlist guide for the current list.
Look for reprints of what you lost
Bandai reprints popular staples into newer products regularly. A card you thought rotated may have a Standard-legal printing available cheaply.
Confirm the format before you travel
Event listings state Standard or Extra. Check it before building, because assuming is how people arrive at a venue with an illegal deck.

Frequently asked questions
- Does the One Piece Card Game have rotation?
- Yes. Since 1 April 2026, Standard Regulation uses the Block Number System and keeps the three most recent blocks legal, rotating the oldest block out roughly once a year. Extra Regulation has no rotation.
- Which sets are Standard legal?
- The three most recent blocks. Block 1 (OP-01 to OP-04) has rotated out; Blocks 2, 3 and 4 (OP-05 through OP-16) are legal, and OP-17 begins Block 5. The block icon printed on each card is the definitive answer.
- Where is the block number printed on a card?
- In the lower-right corner of the card frame, as a small numbered icon. It appears on cards from every product type, including starter decks, extra boosters and promos.
- Are my rotated cards worthless now?
- No. They remain fully legal in Extra Regulation, and collector-driven cards such as alternate arts and Secret Rares are priced on scarcity rather than legality. Competitive staples do lose value when they rotate out.
- Can a rotated card come back to Standard?
- Yes. If Bandai reprints it in a newer product with an updated block icon, that printing is Standard legal. The older printing stays where it is, so both exist side by side.
